To all whom it may concern:

Be it known that I, GLENN CULBERTSQN, a citizen of the United States,residing at Frankfort, in the county of Clinton and State of Indiana,have invented certain new and useful Improvements in Grain- Shockers, ofwhich the following is a; specification.

This invention relates to harvesting machines and more particularly to ashocker for attachment to a binder on grain harvest,- ing machine.

The primary object of this invention is the provision of bundle or sheafretaining members which are attached to-a binderand positioned so as toreceive the sheavesi mmediately after they are deposited or; ejectedfrom the knotting mechanism of the, binder,

for retaining them until a sufficient number has accumulated for forminga shock, after which the retaining members are actuated forautomatically positioning the sheaves in upright positions upon thesurface ofthe field.

Another object of this invention is the provision of means associatedwith the sheaf retaining members for firmly seating the shocks upon theground so as to prevent them from falling over, and also suitable meansfor returning the sheaf retaining members to a receiving and retainingposition adjacent the knotter of the binder.

With the foregoing and other objects. in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated, inthe-accompanying drawings and claimed.

In describing the invention, in detail reference will be had to theaccompanying drawings wherein like characters of reference designatelike or corresponding parts throughout the several views, and in whichFigure 1 is a view showing the improved shocker in elevationiandapplied. to a grain harvester such as is. commonly known as a binder.Fig. 2 is a central longitudinal sectional view through the improved,grain i; shocker. Fig. 3 is a top plan View. -Fig. 4c

is an end view showing parts thereof broken away. Fig. 5 is a section onthe line.55 of Fig. 2.

Referring more particularly to the draw- ,11 ings, 1 designates a grainharvester of the type commonlyknown as a binder and such as.-,is,- used.in the cutting or harvesting of grains such as'wheat, oatsor the likewherein the-heads of the grain are carried upon. straw, stems and theharvester l hasv theusual type of tying and knotting mechanism 2, whichis. positioned above the deck 3 as is common, in the construction of,harvesters of this nature. The grain after it has been out passesupwardly over the conveyer ,4 to, the deck 3 where it is; tied intosheaves, which sheaves are deposited or ejected from the deck 5; intotheretaining member, 5.

The retaining member 5 is constructed of two. members 6and;7, whichmembers; are. mounted upon; av shafts and they have a plurality ofarcuate prongs. 9. formed thereupon and extending toward the deck 3,

which prongs, a-reqnorma-lly holdin open position so as to receive andretain the s e ves; ofigrain stra therein.

The members 6 and 7 have arms.11,1 2-, 13 an 14 formed thereupon andextending in opposite directions tOr theprongs: 9, the arms, 11 and,12ybeing formed upon the member 7, while, the ar1ns;l3, and 14 areformed upon the member 6. These arms extend outwardly from the bearings15 which; are formed upon: the members 6 and 7; and receive the shaft 8,and they curve inwardly having their terminal ends positioned inparallel relation, with; each. other and connected to, links 16. Theportions of the members 6,and 7, which are mountedeupon he shaft nd havehe a sand prongs,

projecting outwardly therefrom are positioned one within. the other asis clearlyshown in Fig. 1 of the drawings, so;-as to permit ofthepivotal movement of the-n embers. upon the shaft 8,,withoutone ofthem retarding the actionof the, other.

,The, links 16 are pivotally connected, to a sleeve 17 which sleeve isslidably keyed upon a shaft 18 and 1151815111 annular groove. 19 formedtherein near one end thereof, in which groove the end 20 of theactuating ar1n21 is seated. The-actuating arm 21 is pivotally supportedby a brace 22.

The shaft 18 has a traction wheel 25 ing 26. ;T he clutch; cone, 28: is,keyed upon the shaft 18 outwardly of the sleeve 17 and it is providedwith an annular groove 29 in which groove are seated the arcuate arms 30of the lever 31.

The lever 31 is pivotally connected at 32 to the frame 33, which frameextends transversely about the traction wheel 25, having a bearing 34formed thereon for the reception of the terminal end of the shaft 18,and it is connected in any suitable manner to the frame of theharvesting machine 1. The lever 31 has connection with a rod 35 throughthe medium of a link 36. The rod 35 extends longitudinally along theportion of the frame 33 which extends toward the binder frame, and ithas connection with a manually operable lever 37 which is mounted uponthe frame of the binder in a position for convenient actuation by theperson seated upon the binder.

The shaft 8 has its terminal ends bifurcated and rollers 39 and 10rotatably seated in the bifurcated ends thereof, which rollers travelupon the inner surface of a substantially circular track 411. Thecircular track 11 is positioned vertically, and it is supported by rods12, which rods are in turn attached to the frame 33 in any suitablemanner such as is shown in Figs. 2 and 3 of the drawings.

The shaft 18 has a spiral spring 53 coiled thereabout, one end of whichspiral spring abuts the outer end of the collar 17, while the other endengages a pin or collar 51 which is carried by the shaft 18, and thespring is connected to the pin 54: so that it will be tensioned upon therotation of the shaft in one direction.

The free terminal end of the actuating arm 21 has a roller 55 rotatablymounted thereupon, which roller has peripheral engagement with a cam 56,which cam is rigidly carried by the shaft 18 for rotation therewith, foractuating the arm 21 upon its pivotal point for sliding the sleeve 17upon the shaft 18.

' The track 41 as clearly illustrated in Fig. 4: of the drawingsconstitutes two sections 61 and 62, which are of different diameters,and the section 62 being of increased diameter with respect to thesection 61. The sections 61 and 62 are connected by straight portions63, which straight portions will provide an abrupt drop to the shaft 8and the sheaf carrying mechanism carried thereby for firmly setting thesheaves upon the ground for forming a shock.

In the operation of the improved shocker, or bundle carrier the bundlesor sheaves of grain are deposited in the retaining member 5, between thearcuate prongs 9 of the members 6 and 7 and when the desired number ofsheaves for making a shock are positioned within the retainer 5, thelever 31 is actuated through the medium of the manually actuated lever37 and the clutch cone 28 is moved into the clutch cone bearing 26 sothat the shaft 18 will rotate synchronously with the traction wheel 25and this will cause the rotary movement of the shaft 8 about the track41 with the shaft 18 as a central axis thereof. The friction of theengagement or guiding of the ends of the shaft will be materiallydecreased by the rollers 39 and =10.

The rotation of the shaft 8 about the shaft 18 as an aXis therefor willrotate or move the members 6 and 7 from a vertical to a horizontalposition so that the sheaves retained by the arcuate prongs 9 thereofwill be moved from a horizontal to a. vertical position for depositingupon the ground to form a shock. During the rotation of the shaft 18,the roller 55, carried by the bell crank 21 will travel about theperiphery of the cam 56, thereby rocking the bell maul: 21 and slidingthe sleeve or spider 17 lorgitudinally upon the shaft 18, which willmove the arcuate sheaf carrying arms 6 and 7 outwardly, spreading them,so that when they reach a vertical position, the sheaves may bedeposited therefrom, butts downward upon the ground. The spring 53, actsfor automatically returning the spider or sleeve 17 and the bell crank21 to their normal positions, when the roller 55 engages the narrowportion of the cam 56.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation of the improved grain shocker will be readilyapparent to those skilled in the art to which this invention appertainsand while in the foregoing descripticn the principle of the operation ofthis invention has been described, together with various features ofconstruction, it is to be understood that minor features ofconstruction, combination, and arrangement of parts may be altered tosuit practical conditions, provided such alterations are comprehendedwithin the scope of what is claimed.
